It looks as though Samsung is making some business decisions to move away from supplying Apple. It makes sense with Apple coming after them with legal action.
In October, Samsung terminated its LCD contract with Apple. And that is big, because Samsung is Apple’s largest supplier of displays, shipping tens of millions to the company per year. Now Samsung has stopped supplying Apple with batteries for the iPad and MacBook laptops. Ouch!
We don’t have a lot of details, but it seems that Samsung has stopped the supply rather than Apple initiating it. Apple has now called upon other manufacturing partners to make up the difference, which would be millions of batteries. This will hurt Apple more than Samsung.
